How important was the invention of the lithium-ion battery?

Liberia: The West African nation of Liberia was never formally a US colony, but from 1816 to 1847 it was administered by the American Colonization Society — founded to return freed American slaves to Africa. Liberia in 1847 became the first independent republic in Africa (and just the second Black republic after Haiti). Its first president was Joseph Jenkins Roberts, a former slave from Virginia. With a similar flag and a US-modeled Constitution, Liberia has remained independent despite several periods of extreme turmoil, including two civil wars.

As the coronavirus continues to sweep across the United States, hospitals around the country are seeing a crush of COVID-19 patients requiring urgent care.
